I set my E75 up with Exchange push mail a few weeks back and it has been behaving itself nicely until yesterday.  During an update the screen suddenly started flashing, basically redrawing itself over and over.  The only way I could get it to stop was to do a hard reset which of course means full set up of everything again. 

Everytime I set it up it works fine until I set it ExchangeMail again.  When it starts updating it all goes well until it reaches Monday's e-mail and then it goes into its redraw routine.

I can't see anything particularly odd about e-mails received on Monday.  I have just deleted them all but have yet to reset up the phone.  I'm just wondering if anyone else has experienced this or has heard about this and knows of a permanent solution.
